Medigap Guide: 7 Actionable Insights on Medicare Supplement Insurance

The Centers for Medicare and Medicaid Services report that approximately 67.3 million adults in the U.S. are enrolled in Medicare. Navigating the complexities of Medicare can leave you with unexpected medical expenses that aren’t covered by Original Medicare. Without additional coverage, these out-of-pocket costs—like copayments, coinsurance, and deductibles—can add up quickly, potentially leaving you financially vulnerable. 

Medigap (also known as Medicare Supplement Insurance) fills these gaps, offering comprehensive coverage to reduce your healthcare costs and provide peace of mind, so you can focus on your health, not your bills. In this blog, we’ll answer frequently asked questions on Medicare Supplement Insurance to help you understand this essential coverage.

Key Takeaways:

• Medicare Supplement Insurance helps cover out-of-pocket costs not paid by Original Medicare.
• To enroll in a Medicare Supplement plan, you must have both Medicare Part A and Part B.
• There are several plan options available, each offering different benefits.
• Individuals with Original Medicare, frequent healthcare needs, or those who travel often may benefit from this additional coverage.
• Apply for a Medicare Supplement plan during the Medicare Open Enrollment Period to secure guaranteed coverage.

1. What is Medigap insurance?

Medigap is a type of supplemental insurance designed to help cover some of the out-of-pocket costs that Original Medicare (Part A and Part B) doesn’t cover. While Original Medicare provides solid coverage for hospital and medical services, it doesn’t pay for everything. This includes costs like copayments, coinsurance, and deductibles. Medicare Supplement Insurance helps fill these gaps, reducing your overall healthcare expenses.

Medigap overview:

• Medigap is insurance that works alongside Original Medicare (not Medicare Advantage).
• It covers out-of-pocket costs like copayments, coinsurance, and deductibles.
• You must have Part A and Part B of Medicare to be eligible.

For more information, you can visit the official Medicare.gov website.

2. How does Medigap work?

Medigap works by filling the gaps left by Original Medicare, which can leave beneficiaries with significant out-of-pocket expenses. Here’s how it works:

1. Medicare Pays First: When you receive healthcare services, Medicare will pay its portion first, as it would with any regular claim.
2. Medigap Pays Second: Once Medicare has processed the claim, your Medicare Supplement Insurance policy will step in to pay for any remaining eligible costs that Medicare didn’t cover, depending on the plan you choose.

This means that with Medigap, you could avoid surprise medical bills by having a more predictable and comprehensive coverage plan.

Medigap vs. Medicare Advantage

It’s important to note that Medigap works only with Original Medicare (Part A and Part B). It cannot be used in conjunction with Medicare Advantage (Part C). While Medicare Advantage plans often offer additional benefits like prescription drug coverage, vision, and dental, they operate differently from Medigap.

3. What does Medicare Supplement Insurance cover?

Medigap policies cover a range of out-of-pocket costs, but the specific benefits depend on the plan you choose. Here are some of the common expenses Medicare Supplement Insurance helps cover:

• Coinsurance for hospital stays (Part A)
• Copayments for doctor visits (Part B)
• Deductibles for hospital and medical expenses (Part A and Part B)
• Emergency foreign travel health care
• Blood for transfusions (up to the first three pints)

Some plans also cover skilled nursing facility care, Part B excess charges, and at-home recovery benefits. It’s essential to check the details of the specific plan you are considering, as coverage can vary. You can use Medicare’s plan finder to compare Medicare Supplement Insurance plans available in your area.

4. What are the different plans?

Medigap plans are standardized by the federal government and labeled with letters (Plan A, Plan B, Plan C, etc.). Each plan offers a different combination of benefits, with Plan F and Plan G being the most popular choices due to their comprehensive coverage.

Here’s a quick overview of some of the most common Medicare Supplement Insurance plans:

• Plan A: Basic coverage for hospital and medical costs.
• Plan F: Comprehensive coverage, including all the benefits provided by other plans and covering your Part B deductible (currently only available to those eligible for Medicare before 2020).
• Plan G: Similar to Plan F but excludes the Part B deductible.
• Plan N: Covers most out-of-pocket costs but requires copays for some doctor visits and emergency room visits.

Each plan is offered by private insurance companies, and prices can vary based on factors like location and your personal health. For more details about plan options, visit Medicare’s Supplement Insurance page.

5. Who needs Medigap insurance?

Medigap insurance is not required by law, but it can be a wise investment if you want to lower your out-of-pocket healthcare costs. Here’s who should consider this type of plan:

People with Original Medicare

If you’re enrolled in Original Medicare (Part A and Part B), Medigap is a great way to reduce your out-of-pocket expenses. It works in tandem with Medicare to provide you with more comprehensive coverage.

Individuals with Frequent Healthcare Needs

If you have ongoing medical conditions or anticipate needing frequent medical services, Medicare Supplement Insurance can help reduce the financial burden. It’s particularly useful for covering things like hospital stays, doctor visits, and specialist care.

Those Who Want Predictable Healthcare Costs

Medigap is ideal for people who prefer the stability of knowing exactly how much they’ll need to pay for healthcare. By reducing deductibles, coinsurance, and copayments, this plan can make your healthcare expenses much more predictable.

Travelers

Medigap Plan C and Plan F cover emergency foreign travel health care, which is ideal if you travel abroad frequently and want additional coverage. For more information on foreign travel coverage, check out this Medicare.gov article on foreign travel emergency coverage.

6. When can you apply for Medigap insurance?

You can apply for Medigap during the Medicare Open Enrollment Period, which begins the month you turn 65 and lasts for six months. During this period, you are guaranteed the ability to buy a policy without medical underwriting, meaning your health status cannot be used as a reason to deny you coverage or charge you higher premiums.

It’s also possible to apply outside of the Open Enrollment Period, but insurers may consider your health history and can charge higher rates or deny coverage if you have pre-existing conditions. For more details on the enrollment period, visit Medicare’s enrollment page.

7. Is Medigap worth it?

Medigap is a valuable option for many Medicare beneficiaries, especially if you want to minimize unexpected healthcare expenses. While these types of policies come with an additional monthly premium, the benefits of comprehensive coverage and reduced out-of-pocket costs can outweigh the expense—particularly for those with chronic health conditions or those who need frequent medical care.

Before enrolling, it’s important to compare the different plans available in your area to find one that meets your needs and budget. You can start by using this resource to Compare Care Near You.

By knowing what it covers, how it works, and whether you need it, you can ensure that you’re fully covered when it comes to your healthcare needs.

If you’re considering Medicare Supplement Insurance, take the time to research different plans, compare premiums, and consult with a licensed insurance agent to make the best choice for your health and budget. You can speak with a licensed agent on the Medicare.gov website.
